IMPRovnD MQRTAR.

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom it 'may concern.:

being had to the accompanying drawings, and to the letters of referencemarked thereon, which form a partof this specification, and in which isrepresented a perspective view of my improved mortar.

The nature of my invention consists in the employment, in connectionwithra mortar', of a revolving grooved platform or disk, rotating on acircular rail, secured to-a ame or table, and operated by means ot' abelt passing over two pulleyssecured directly/'opposite it, and thenceover another pulley or driving-wheel, attached to a crank-shaft, havingits bearings in the upper ends of vuprights 'seein-ed on each side ofthe' disk and mortar; in the lemployment of a sliding frame or cap,which is furnished, near and at its centre, with openings, and on itslower side with two cleaners; and also, in hingingv the pestle to a rodor bar, connecting with the crank-shaft above described.

A To enable others. to avail themselves ot' the beneiits of myinvention, I will describe its construction and operation.

In the accompanying drawing,N N represent two boards, crossing eachother, and united at the centre, thus forming a frame or table.

Upon this frame is secured a circular rail, formed with fianges bentdown and penetrating the wood.

K is a circular' platform or disk, which is excavated or recessed on itsupper surface, to receive the base of. the mortar A, in order to holdsaid mortar thereon, and provided on its circumference with a groove,the object of'which will be referred to hereafter.

M M are two uprights, secured on each side of disk or platform K, andmade narrowA on a-portion o ftheir surface, near the upper end, as seenin the drawing.

C represents `a cap or frame, which is made so as to tit or rest at itsends on the shoulders of the uprights' M, formed by its reduction, andsliding up and do'wn This cap or frame is provided, at and near itscentre, with openings, D and l?, the opening D being designed for thepestle to pass through while working in connection with the crank-shaftE, and openings l to allow the pestle to be attached firmly, by pin orotherwise, to the cap While in use Aforgrinding extra hard substances.

L .L are' two cleaners, secured to the lower side of cap C by means ofthumb-screws, and made 4to extend down in contact with the inner surfaceof mortar A, to prevent the mortar from becoming clogged.A

B represents the pestle, which is made to extend up through the openingI) of cap C, and hinged or pivoled to the connecting-rod or bar. F bymeans of ,pin or key G, saidipestle and-connecting-rod or bar beinglprovided with adjusting-holes, for the purpose of laising and loweringthe said pestle, when desired.

The connecting-rod Fis-attached to the looped or cranked part of shaft Eby means of a band or strap passing around the said shaft, andconnecting at each 'end with the rod F.

E designates the crank-shaft, which has its bearings in the upper endsof uprights M, and supplied at one end with a wheel, to which isattached a handle, e, and provided at its oppositevend with adriving-wheel or pulley, H, over which passesfa belt or band, I,extending down over4NI two other pulleys, J J, having their bearings onan axle, j, secured to lower part of one of the uprights M, and thencearound the groved re vol-ving platform or disk K, the object of saidband or belt being to communicate a rotatory motion to the circularplatform ordisk K. A

It will be observed that the rotating disk and mortar can bothbere-moved from their original position, when desired, by merel yraising the sliding cap or frame G, with itscleaners.

What I claim', and desire to secure by Letters Patent, is-

1. The circular-grooved platform or disk K,rotated on a circular railsecured to the platform or table N N', in combination with' the mortarA, operated and arranged substantially as and for the purpose set forth.

2. The sliding frame or cap C, provided with the openings l) and P andcleaners L L, in combination with the uprights M and frame or boards NN', all arranged and operated substantially as and for the purpose setforth.

3. The pestle B, hinged to the connecting-rod F of crank-shaft E,arranged and operated substantially as described. l

4. Frame orboards N N', uprights M, axle4 j, pulleys J J, cap or slidingframe C, revolving disk or plat form K, mortarA, cleaners L L, pestleB,- connectingrod F, pin G, crank-shaft E, handle e, driving-wheelorpulley 'H,and bandeor belt I, when combined, arranged, and operatedsubstantially as and for the purpose set forth. In testimony thatI-claiin the foregoing as my own, I afiix my signature, in presenceoftwo witnesses.
